Major League Baseball has reported its most recent move to cash on the NFT craze: official blockchain-based versions of classic Topps baseball cards. Topps is selling the new NFT baseball cards through the WAX blockchain, which the company has utilized for its soonest blockchain-based collectibles.

The first “Series 1” cards will be sold beginning on April twentieth, with 50,000 standard packs (containing six cards for $5) and around 24,000 premium packs (offering 45 cards for $100) set to be sold in the first wave. Topps is also offering a free “exclusive Topps MLB Opening Day NFT Pack” to the initial 10,000 users who sign up for email alerts for new releases.

It’s a similar idea to the NBA’s white-hot Top Shot NFTs, which offer fans purchasable video clips (called Moments) in card-like packs. Top Shot Moments are as of now an enormous business — some have sold for upwards of $200,000, and in excess of 800,000 accounts have yielded more than $500 million in sales until this point.

And keeping in mind that the Topps baseball cards will not be full-fledged videos like Top Shot Moments, the organization is wanting to exploit of the digital nature of the NFT cards by adding things like animated backgrounds or holographic effects on rarer cards. It’s not the MLB’s initial dunk into digital money, either: the league has experimented with Ethereum-based blockchain bobbleheads in its MLB Champions game, as well. The Topps cards guarantee a more traditional style of collectible, in any case.

Topps’ collectible baseball cards have been around for decade and bring a level of name recognition and respectability to the world of collectibles that other NFT endeavors may need. However, it’ll actually need to convince fans that the digital versions of those cards are a sound investment and not simply an bubble that’s waiting to burst.
